The present invention relates to the use of a polyurethane adhesive in the manufacture of film/foil-coated furniture. The adhesive consists of two components, the first component comprising at least two different polyurethanes which comprise carboxyl groups, and the polyurethanes comprising units derived from polyester diols and units derived from polyether diols, the weight quantity ratio of the sum total of all units derived from polyester diols to the sum total of all units derived from polyether diols being in the range from 1:9 to 9:1, and the second component comprising at least one silane compound reactive toward carboxyl groups.

Use of polyurethane adhesive formed from polyester diols, polyether diols and silane compounds in the manufacture of film/foil-coated furniture

A description is given of an adhesive comprising two components, the first component comprising at least two different polymers of which at least one contains carboxyl groups. One of the polymers is selected from polymers which are capable of forming crystalline domains and copolymers of ethylene and vinyl acetate, and the second polymer is an amorphous polyurethane, the quantitative weight ratio of first polymer to second polymer being from 2:8 to 8:2. The second component comprises at least one silane compound that is reactive toward carboxyl groups. The adhesive can be used to produce film-laminated moldings for automobile construction which feature high resistance to climatic cycling.

A pressure sensitive adhesive comprising an aqueous dispersion of a polymer, said dispersion comprising, besides the polymer, silicon compounds selected from polymeric silicates, water-soluble alkali metal silicates (waterglass), silanes, and silicones obtainable from the silanes by condensation.

An apparatus for the application of a flowable medium ( &prime;) from a stock chamber ( ) to a surface ( ) being moved along the apparatus, and to the use of an apparatus of this type. The stock chamber ( ) partly covers the surface ( ), with formation of a sealing gap ( ) and an exit gap ( ). In order to prevent the formation of air bubbles in the medium ( &prime;), it is proposed to divide the stock chamber ( ) into a pre-chamber ( ) and a main chamber ( ). A dividing element ( ) which, together with the surface ( ), limits a dividing gap ( ), is arranged between the chambers. Various shapes of the dividing element are proposed. The apparatus is particularly suitable for the application of a polymer dispersion to the surface ( ). A process for operating an apparatus of this type is also described.

Device and method for applying a flowable medium onto a moving surface

An aqueous composition is essentially free of organic solvents, plasticizers and additional tackifiers and contains water and 20-99% by weight of a polymer and 1-80% by weight of a filler, the percentages by weight being based on the sum of the components of the aqueous composition, with the exception of water.

Method for adhering a floor covering to a floor with a floor adhesive

Readily filterable and deodorizable aqueous dispersions of pressure-sensitive adhesive, especially for self-adhesive labels, having solids contents of more than 65%, can be prepared with readily reproducible properties by copolymerizing esters of acrylic and/or methacrylic acid in the presence of less than 50 ppm of inhibitor and, preferably, in the presence of from 0.01 to 5% by weight of reducing agent by a special emulsion technique. The highly concentrated pressure-sensitive adhesive dispersion, subsequently deodorized with steam, is free from coagulum and seediness.

Production of highly concentrated adhesive dispersions and their use

Volatile components are eliminated from polyacrylate melts by distilling off the volatile components by a process in which the volatile components are distilled off under reduced pressure, entraining agents are added to the melts at above 100.degree. C. and the melts are simultaneously circulated.

Elimination of volatile residues from polyacrylate melts

An aqueous polymer dispersion with a solids volume concentration of at least 50% by volume is obtainable by polymerizing monomers by the method of free radical aqueous emulsion polymerization with the addition of at least one fine and at least one coarse aqueous starting polymer dispersion.
